# TS971ILT

**STMicroelectronics** · Operational Amplifier · SOT-23-5

TS971ILT from STMicroelectronics, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Output | output | Amplifier output with rail-to-rail swing (VOH 2 V min, 2.4 V typ; VOL -2.4 V typ, -2 V max at VCC = ±2.5 V, RL = 2 kΩ). |
| 2 | VDD | power_in | Negative supply (ground in single-supply use); input voltage range is VDD - 0.3 V to VCC + 0.3 V. |
| 3 | Non-inverting input | input | Non-inverting input with common mode range VDD + 1.15 V to VCC - 1.15 V and differential input voltage limited to ±1 V. |
| 4 | Inverting input | input | Inverting input with common mode range VDD + 1.15 V to VCC - 1.15 V and differential input voltage limited to ±1 V. |
| 5 | VCC | power_in | Positive supply with operating range 2.7 to 10 V and absolute maximum of 12 V. |

## CAD (KiCad official)

- Symbol: `TS971ILT`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `ts971ilt-etched.step` / `ts971ilt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ts971ilt.step` / `ts971ilt.glb` are the bare package body.
